I have no question in my mind that Bing will continue to do great things with the presentation of search. But no matter what you do, the thing people really want is to find the best results to their queries possible.
From my own usage, Bing is definitely a close second to Google in accuracy for what I was looking for. Others may find their results to be better, I cannot speak to that. But even with such things as Visual Search for Bing, I come back in asking how much better the results are truly?
Bing does a nice job at helping to sift through a number of sites, but sadly I have found that it is not nearly as on target for my own search needs despite these efforts. Pretty is not more accurate, sorry.
